I'm using this library via Home Assistant and I occasionally see LoginError in the log. It always resolves itself within a few seconds, I'm just trying to figure out what causes it. I first posted in home-assistant/core#85859.

It seems like this library tries Basic Auth first, which always fails (silently), and then it tries Digest Auth which usually succeeds. I've been trying to reproduce the 401 error with DigestAuth by simulating network congestion with iptables but so far I can't. I only notice this happening every few days.

My cameras are model IP5M-T1179EW, but that log snippet came from someone else; I'm not sure what model that is.

Here is my log when the occasional error happens. The model is Amcrest Doorbell AD410. The password does not contain any special chars, as suggested this would be the cause.

@junalmeida I think the ReadTimeouts are irrelevant, it just suggests your network is congested or the camera is slow to respond. This LoginError seems to happen randomly with any call. Besides LeLensMask, I've also seen it on getCurrentTime (and probably others, but I haven't been tracking it closely).

I added _LOGGER.debug('auth: %s', vars(self._token)) to line 344 just before each get call and I see some interesting things, but I don't know what to make of this.

It fires 7 async queries at the same time (within 300ms), of which 6 use the same nonce. The one that fails is the only one with a different nonce.

The _nonce_count is never 1, it always starts at 2.

I am seeing the same problems. I also noticed that when Home Assistant (using the library) tries to connect with my doorbell and the log show these timeout errors, I can manually connect with the doorbell's api using PostMan without any problem. All the times this happens. I think that about 50% of the time HA fails to connect with the doorbell when it reboots.
I'm very sure there's no congestion on my local network whatsoever.

I just had to reconnect the doorbell and Home Assistant was not able to reconnect:

I see this same issue with an AD410. Intermittent login errors.
